1. Classification of Movement Skills
Classification | Definition | Key Characteristics | Examples |
|---|---|---|---|
Fundamental Movement Skills (FMS) | Basic movement patterns that form the foundation of all sport skills. | Usually developed in childhood and are required before learning sport-specific skills. | Running, jumping, throwing |
Sport-Specific Skills | Advanced skills used in particular sports. | Built from fundamental movement skills and refined through practice. | Tennis serve, soccer kick, basketball shot |
Fundamental Movement Skill Types
Type | Description | Examples |
|---|---|---|
Stability Skills | Involve balance and body control. | Balancing, twisting, landing |
Locomotor Skills | Allow the body to move through space. | Running, hopping, skipping |
Manipulative Skills | Involve controlling objects using hands or feet. | Throwing, kicking, striking |
Extra knowledge
Importance | Explanation |
|---|---|
Foundation of sport | Sport-specific skills develop from FMS |
Participation | Poor FMS development can reduce sport participation later in life |
Physical literacy | Improves confidence and willingness to play sport |
Open vs Closed Skills
Skill Type | Definition | Environment | Performer Control | Examples |
|---|---|---|---|---|
Open Skills | Skills performed in changing environments. | Unpredictable | Low control | Football pass, hockey tackle |
Closed Skills | Skills performed in stable environments. | Predictable | High control | Golf swing, gymnastics routine |
Gross vs Fine Motor Skills
Skill Type | Description | Muscle Groups | Precision | Examples |
|---|---|---|---|---|
Gross Motor Skills | Large movements involving large muscles. | Large muscles | Low precision | Running, jumping |
Fine Motor Skills | Small precise movements. | Small muscles | High precision | Archery, darts |
Discrete, Serial and Continuous Skills
Skill Type | Definition | Characteristics | Examples |
|---|---|---|---|
Discrete | Skills with clear beginning and end. | Short duration | Tennis serve |
Serial | Several discrete skills linked together. | Sequence of movements | Gymnastics routine |
Continuous | Skills repeated continuously without clear start/end. | Rhythmical movement | Running, swimming |
2. Link Between Motor Skill Development, Participation and Performance
Factor | Impact on Participation | Impact on Performance |
|---|---|---|
Motor skill competence | Increases confidence and enjoyment | Improves technique and efficiency |
Poor skill development | Reduces willingness to participate | Limits performance potential |
Early skill development | Encourages long-term sport involvement | Builds advanced skill pathways |
3. Sociocultural Factors Affecting Skill Development
Enablers
Factor | Description | Example |
|---|---|---|
Parental support | Parents encourage and fund participation | Paying club fees |
Peer encouragement | Friends motivating participation | Playing sport with friends |
Access to facilities | Availability of venues and equipment | Local sports clubs |
Role models | Athletes inspiring participation | Professional athletes |
Government funding | Financial support for sport | Community sport programs |
Barriers
Factor | Description | Example |
|---|---|---|
High cost | Expensive equipment or club fees | Ice hockey gear |
Travel distance | Long travel to training or competitions | Rural athletes |
Low physical literacy | Lack of skill confidence | Fear of embarrassment |
Time constraints | Work, school or family commitments | Busy schedules |
4. Stages of Learning
Stage | Characteristics | Errors | Coaching Strategies |
|---|---|---|---|
Cognitive Stage | Beginner learning what to do | Many errors (stiff unrelaxed) | Demonstrations, simple instructions |
Associative Stage | Refining technique | Fewer errors (detect the cause of some errors.) | Practice with feedback |
Autonomous Stage | Skill becomes automatic | Very few errors (detect and correct errors.) | Game-like training and tactics |
5. Theories of Skill Acquisition
Linear (Direct Coaching)
Feature | Explanation |
|---|---|
Coach centred | Coach directs learning |
Structured drills | Repetition of technique |
Limited decision making | Athlete follows instructions |
Non-Linear (Constraints-Based)
Constraint Type | Description | Example |
|---|---|---|
Individual constraints | Athlete characteristics | Height, strength |
Environmental constraints | Surroundings | Weather, noise |
Task constraints | Rules or equipment | Court size, player numbers |
Key concept
Learning occurs through interaction between these constraints.
6. Psychological Skills
Confidence
Level | Characteristics | Performance Effect |
|---|---|---|
Low confidence | Fear, doubt | Poor performance |
Optimal confidence | Positive mindset | Best performance |
Overconfidence | Lack of focus | Performance decline |
Confidence Strategies
Strategy | Description |
|---|---|
Positive self-talk | Encouraging thoughts |
Mental imagery | Visualising successful performance |
Preparation | Training to build belief |
Arousal
Level | Characteristics | Performance |
|---|---|---|
Low arousal | Bored, tired | Poor performance |
Optimal arousal | Focused and alert | Best performance |
High arousal | Anxiety and tension | Poor coordination |
Arousal Regulation Strategies
Reduction Strategies | Promotion Strategies |
|---|---|
Deep breathing | Energising imagery |
Relaxation | Music |
Meditation | Positive self-talk |
7. Scheduling of Practice
Practice Type | Description | Best For | Example |
|---|---|---|---|
Part Practice | Skill broken into components | Beginners | Learning tennis serve stages |
Whole Practice | Skill practised fully | Simple skills | Swimming stroke |
Practice Distribution
Type | Description | Advantages |
|---|---|---|
Distributed Practice | Short sessions with rest | Less fatigue, better learning |
Massed Practice | Long sessions with little rest | Efficient for experienced athletes |
Practice Variability
Practice Type | Description | Best For |
|---|---|---|
Blocked Practice | Repeating same skill | Beginners |
Random Practice | Skills performed in varied order | Advanced learners |
8. Feedback
Feedback Type | Definition | Example |
|---|---|---|
Intrinsic Feedback | Internal sensory feedback | Feeling balance |
Augmented Feedback | External feedback | Coach advice |
Types of Augmented Feedback
Type | Description | Example |
|---|---|---|
Knowledge of Results (KR) | Outcome of performance | “You scored the goal.” |
Knowledge of Performance (KP) | Technique information | “Keep your elbow higher.” |
9. Biomechanical Principles
Concept | Definition | Formula/Explanation |
|---|---|---|
Force | Push or pull that changes motion | F = m × a |
Torque | Force causing rotation | Torque = Force × lever arm |
Momentum | Amount of motion an object has. | p = mass x velocity |
Impulse | Change in momentum | Impulse = Force × Time |
10. Speed, Velocity and Acceleration
Concept | Definition | Formula |
|---|---|---|
Speed | time taken to cover a distance. | Speed = distance ÷ time |
Velocity | Time taken to change position. | Velocity = displacement ÷ time |
Acceleration | Change in velocity over time | Acceleration = change in velocity/ change in time |
11. Newton’s Three Laws of Motion
Law | Description | Sport Example |
|---|---|---|
First Law (Inertia) | Object stays at rest or constant motion unless acted upon by force | Ball stays still until kicked |
Second Law (Acceleration) | Force causes acceleration | Harder kick → faster ball |
Third Law (Action–Reaction) | Every action has equal and opposite reaction | Swimmer pushes water backward |
12. Projectile Motion
Factor | Effect on Projectile |
|---|---|
Angle of Release | Optimal angle maximises distance |
Height of Release | Higher release increases distance |
